Question

Which of the following is not an acid-base neutralization reaction?

A.) NH3 + HCl NH4Cl

B.) HCl + NaBr HBr + NaCl

C.) HCl + HBr H2 + ClBr

D.) 2 HBr + Ca(OH)2 CaBr2 + 2 H2O

Answer 1

HCl + HBr H2 + ClBr is not acid and base reaction.

During electrolysis:
NH3(g) + HCl(aq) = NH4Cl(aq) or
NH3(g) + H3O+(aq) +Cl^1-(aq) = NH4+(aq) + Cl1-(aq)
add OH1- add H3O+
NH4OH + HCl
Hence,
The best answer is :
C.) HCl + HBr H2 + ClBr
